ABSTRACT:
An armoured flexible pipe has an inner liner (3) surrounded by a pressure armour (5, 6) that is surrounded by a tensile armour (7, 8). The pressure armour (5, 6) is constructed from a number of profiles (5, 6, 10, 11, 12, 14, 14a, 14b, 14c) which may engage with each other. In order to obtain optimum functionality, the profiles are shaped as X profiles (14, 14a, 14b, 14c) which are kept together with another type of profile, e.g. C or T type profiles. In one embodiment, the X profiles have an open channel (17). In this way gas or liquid, such as rinsing fluid, may be pumped through the armour layer, from one end of the pipe to the other end. In particular, the armoured flexible pipe is useful for conveying fluids such as water, ammonia, hydrocarbons, etc.
